Creating custom controls

[Kyle Fitzgerald]

I've started a web control library project and can build
my own controls to add to the toolbox in the .NET
environment. The problem I'm having is I want to create a
control just like the HTML table where I could drag my
control on the page and then drag and drop other controls
into the cells of the table. I've tried creating my own
and I tried to inherit from
system.ui.htmlcontrols.htmltable but I can not get it to
have the borders and cells when I drag my control onto a
form. It just says [xxxTable "xxxTable1"] on the
control. Does anyone have any suggestions on how I might
make a control so developers can drop other controls into
my table control. Also, I'm trying to create my own b/c I
want to limit the functionality a develope can have with
the table and I only want them to start with one row and
two cells.

Thanks in Advance

Hi Kyle,

You'll need to deal with design-time stuff. Take a look at the docs for
everything related to design-time, ie ControlDesigner, etc.

Hi Kyle,

You need to create a Custom Designer class for your control. Here is the URL
of an article in the .Net SDK on developing Custom Designer classes:
